# How to validate the VAT summary of your documents

Checking that the VAT on your documents has been digitized correctly is important for your accounting. Follow these steps:

## Steps to validate a document's VAT

1. **Go to the Documents module**

2. **Open the document you want to review**

3. **Find the VAT summary:**
   - If the document is pending validation, you will see the summary in the first step of the validation process
   - If the document has already been processed, go to the document's "Resumen" tab

4. **Check that it matches the original document:**
   - The tax rate (4%, 10%, 21%...)
   - The taxable base (amount before VAT)
   - The VAT amount (tax amount)

5. **If everything matches:**
   - For pending documents: click "Guardar y Siguiente" and complete the validation
   - For already processed documents: no action is needed

6. **If there is an error:**
   - **For pending documents:** Expand "Desglose de IVA", correct the base amount for the corresponding tax rate, and click "Guardar y Siguiente".
   - **For processed documents:** In the "Resumen" tab, click the edit icon (pencil) for the tax rate, change the base, and confirm with the save button.
